I suggest you’ll re-read my post #88.
Most countries with 2nd Register does not tax shipping companies domiciled in the country, but they do tax the people that work in them that is domiciled there.
To maintain a healthy Shipping industry you have to have people with a maritime background to work both on ships and ashore. To obtain that you have to have ships under your flag where people can get that training and background.
A mix of ships under the National and 2nd registers ensure that there are a fleet under your flag and maritime trained people to work in Shipping related positions ashore, incl. in regulatory bodies, classification societies and a whole host of associated businesses, such as brokerage, finance, insurance etc.
That the 2nd register allow crews hired from other countries at lower wages doesn’t mean that there are no national seafarers on board. There are many vessels under different flags that have a mix of crews from low cost and high cost countries. Especially in the Offshore segment, where specialized skills and experience is required to be able to obtain charters for the vessels in a highly competitive international market.
The technical standard of the ships does not vary by the flag they fly. They are all built and equipped to meet the same international regulations, although some countries have rules and regulations that exceeds the minimum requirements. That doesn’t changes, whether 1st or 2nd Register.
Merchant ships are now mostly built to standard designs by the same yards, classed and inspected by the same classification societies and compete in the same worldwide market. The flag they fly doesn’t change that.
The main difference is the operational standard, where ISM and STCW is trying to level the playing field.
MOU’s PSC is also helping to detect non-conformities and weed out bad Owners/Managers and Flag States. But all this will only work if all serious players in Shipping and all Flag States are doing their bit.
Here is an article from 2015 about why Norway is trying to attract more ships to their NIS register:
Most of what was being suggested then has now been implemented and the NIS fleet is growing again.
Please don’t kid yourself into believing that Norway is compromising on the standard, or that it is all because the Owners are greedy monsters without any social conscience.
In the Offshore segment most of the Owners are former Fishing Skippers, and/or their offspring.
PS> One of the main Norwegian players in both Fisheries, Offshore Oil & Gas, Shipbuilding and now as Owner of OSVs wasn’t even a Skipper, just a Fisherman)
